Next, the operation will be explained. Program 1 includes “WR
4TE A AFTERCHI J, rWRITE
B AFTERCH2J, etc. are written. rWRITEA AF'TERCHI
J means "Print data A on channel CH1."

When program 1 is executed, SYSOUT file 2
A plurality of pairs of channel numbers and data are stored in .

Friend, the image library 3 is provided with a PCB 4, and the channel number and the row and column of the page indicating the base point of the channel are written in the F'CB4.

In the illustrated example, it is written that the base point of the channel is in the 2nd row and 10th column of the page, corresponding to the channel number CHI, and that the base point of the channel is in the 10th row of the page, corresponding to the channel number CH2. It is written that it is the 20th column.

When the NLP writer 5 is activated, it reads the SYSOUT file 2 line by line and sends data while looking at the PCB 4 and paying attention to the rows and columns.

As a result, data A is written starting from the 2nd row and 10th column of the page buffer 8, and data B is written starting from the 10th row and 20th column.

When one page worth of data is accumulated in the page buffer 8, the NLP writer 5 starts reading the data from the page buffer 8 and sends the data to the Japanese LP 6. Japanese L
When P6 receives this data, it immediately prints the data on LP paper T.

Next, the operation of the NLP writer 5 will be explained in more detail.

The NLP writer 5 performs the operations listed below.

(2) PC from the 1st byte data of record R
B4 is searched to find the position of the page indicated by the channel number in the first byte.

(3) Based on the position of this page, SYSOU
The print data starting from the second byte of the first record R□ of the T file 2 is written to the page buffer 8.

(41 Next, read to the second record R2 shown in Figure 8g5 of SYSOUT file 2.

(5) If the first byte of record R2 of 02 items 0 is a channel number, then the above (2), (3), and (4)
Process. If the skip line is displayed, the horizontal position of the channel in the first line is saved as is,
The print data of record R2 is written at a position on the page buffer 8 that is the vertical position of the previous channel plus the number of lines specified by the skip line display.

In this way, a series of data is printed and the NL
The P writer 5 prints two JOB marks 9 indicating the end of the JOB on the LPP paper 7. Since this JOB mark 9 is usually printed at the perforation, when the paper is in a folded state, the division between each job can be immediately recognized.

8! ! In Fig. 4, when the printing of the data in the page buffer 8 consisting of rGHJ data is completed, the paper is fed for the actual amount of paper, the JOB mark data 9 is read, and the JOB mark 9 is transferred to the LP paper T. The operation of printing is performed twice, and printing of one JOB data is completed.

[Problem to be solved by the invention]

Since the output control method of the conventional line printer is configured as described above, when printing multiple copies of the same format on -page paper, when printing the JOB mark, it is printed at the correct perforation. To do so, the amount of movement must be adjusted in the program with the paper size and current print position in mind, and a movement command commensurate with this must be specified. This specification must be changed every time the contents of print job data 9 change. It is a complicated process that must be done carefully.

If you forget to specify the movement command,
There was a problem in that the JOB mark was printed in the middle of the paper.

This invention was made to solve the above-mentioned problems.
It is an object of the present invention to provide an output control method for a line printer that can control OB mark printing and reduce the number of man-hours for creating a program.

[A precautionary measure to solve the problem]

The output control method for a line printer according to the present invention provides a paper control block that stores information on the number of PCB lines of the format to be printed, the number of lines on the paper to be printed, and information on the base position of the block currently being processed within the paper. The paper control block in this invention automatically controls the paper position by calculating the base position of the next block in the paper. Then, the next block base position information in the paper is calculated, and when the JOB data is completed, the perforation position of the page is automatically calculated.

The method of specifying the channel number for CB4 and the row and column of the page indicating the base point of the channel is exactly the same as in the conventional example.

In this example, the current number of format lines in FCB4 is 15 lines,
The number of paper lines is 2 in the paper line number 13 of the paper control block 12.
On line 0, it is written that the current block base position 14 is on the first line.

When the NLP writer 5 is activated, it reads the SYSOUT file 2 line by line, and sends the data to the page buffer 8 while looking at the rcB4 and being aware of the rows and columns.
Data is written starting from the 2nd row and 10th column of this page buffer 8, and data B is written starting from the 10th row and 20th column.

After reading the data from SYSOUT file 2, the page data is completed and the NLP writer 5
starts reading data from the page buffer 8 and sends the data read from the page buffer 8 to the Japanese LP 6. When the Japanese LP6 receives the data, it immediately prints the data on the LP paper.

Next, the operation of the NLP writer 5 will be explained in detail according to the flowchart shown in FIG.
